Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will occur through the selection of a sealed opaque envelopes that will contain a number. This number will correspond to a medication pack. Patients will be randomised to one of two treatment groups in equal proportion
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will be randomised to one of two treatment groups in equal proportion, crossover after 14 days with washout period dependent on gender (28 days for males; 42 days for females). Capsules for active and placebo are colour matched.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes

Summary
Brief summary
Milk Thistle has been used in medical remedies for 2000 years as a therapeutic herbal medicine in the treatment of acute and chronic liver diseases. Some of its effects have been shown to due to an antioxidant and anti-inflammatory effect. There is also evidence that an active constituent within Milk Thistle called Silibinin inhibits an enzyme that works on the bile pigment called bilirubin which allows its excretion from the body. Inhibition of this enzyme would allow bilirubin levels to rise to produce a condition called ‘mild hyperbilirubinemia’. Many clinical studies demonstrate a dramatic reduction in cardiovascular disease (CVD) and atherosclerosis in patients that is directly attributed to elevated bilirubin levels in the blood. This effect is in part due to the powerful anti-oxidant properties of bilirubin. The aim of this study is to see if taking Milk Thistle extract will increase bilirubin levels and over time, may provide protection from heart disease.
